- Asymptotes of Secant, Cosecant, and Cotangent. To find the x-intercepts and asymptotes of secant, cosecant, and cotangent, rewrite them in terms of sine and cosine. Notice that since secant and cosecant have 1 in the numerator and a trig function in the denominator, they can never equal zero; they do not have x-intercepts. The vertical asymptotes of the three functions are whenever the denominators are zero.

- Consider the triangle below: The hypotenuse in a right triangle is always larger than the adjacent side, so for angles greater than zero but less than 90 the cosine ratio will be less than 1. For angles outside of these limits, the sine ratio can have values from -1 to 1.

- If the covariance is zero, then the cases in which the product was positive were offset by those in which it was negative, and there is no linear relationship between the two random variables.

Sine, Cosine and Tangent in Four Quadrants Sine, Cosine and Tangent in the Four Quadrants. Now let us look at what happens when we place a 30° triangle in each of the 4 Quadrants. In Quadrant I everything is normal, and Sine, Cosine and Tangent are all positive: Example: The sine, cosine and tangent of 30°. Sine.

Is x equals 0 no solution? Zero is an acceptable value for a variable. As a general rule, if you solve an equation and get x equals zero, that's just what it is: zero. There is one solution. Example: 10x +1 = 5x +1. 5x = 1 - 1. 5x = 0. x = 0. There is one solution, zero. If you solve for x and get two solutions, such as 2 and 0, there are two answers.

What do csc, cot, and sec stand for in math? The cosecant is the reciprocal of the sine. The cotangent is the reciprocal of the tangent. The secant is the reciprocal of the cosine. If you have sin x = 3/5, then csc x = 5/3.E: What do csc, cot, and sec stand for in math? Does anyone know what they stand for and what they&#39;re used for? All I know is that they relate to trigonometry in some way.

- A: The overall or net charge of any ionic compound must equal zero. Although ions themselves are either positive (cation) or negative (anion) by definition, the only way they can bond together and form a compound is by seeking an opposite charge.

- Essentially, an exponent that is zero is equal to a variable to the power of an exponent times a variable to the negative power of the same exponent. For instance, x 2 times x-2 is equal to x 2 divided by x-2. Any number divided by itself is equal to one. Zero to the power of zero is a special case, however.

1. Graphs of y = a sin x and y = a cos x The value of the cosine function is positive in the first and fourth quadrants (remember, for this diagram we are measuring the angle from the vertical axis), and it's negative in the 2nd and 3rd quadrants. Now let's have a look at the graph of the simplest cosine curve, y = cos x (= 1 cos x).

What Is a Zero Pair? Conversely, +3 and -2 would not be considered a zero pair because the resultant sum when they are added together would not be zero (+3 + -2 = +1). The main purpose of a zero pair is to simplify the process of addition and subtraction in complex mathematical equations featuring multiple numbers and variables. For example, in the problem 2+6-3-2, the positive 2 and the negative 2 cancel each other out because they are a zero pair, thus reducing the problem to 6-3.

Can the variance be zero? The idea is that if all of your data points are the same then the mean will be the same as every data point. If the mean is the equal to every data point then the square of each point minus the mean would be zero. All of the squared values added up would still be zero.And zero divided by n is still zero. In this case the standard deviation would be zero.he idea is that if all of your data points are the same then the mean will be the same as every data point. If the mean is the equal to every data point then the square of each point minus the mean would be zero. All of the squared values added up would still be zero.

- Take the equation 7x = 0. Based on the zero product property, either 7 = 0 or x = 0. It is known that 7 cannot equal zero, therefore, x must equal zero. Now look at the equation xyz = 0. Even though there are three variables, you can separate the expression on the left side of the equation into two expressions.

Cosecant (csc) - Trigonometry function Cosecant (csc) - Trigonometry function. In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'. Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.

What causes tornadoes? As the air in a vortex is brought closer to the axis of its rotation, the spin increases. At the most basic level, this is what causes all intense atmospheric vortices: tornadoes, hurricanes, dust devils, etc.

- Your have written an answer to a different question: Is x squared equal to 2x squared. That is not the question as it was stated. According to standard algebraic notation, 2x equals 2 X x, not either 2x2 or (2x)2.f the root of 3 - 2x = x, you need to square both sides to get...    3 - 2x = x2    so-x2 -2x + 3 equals zero. You can factor this out as: (x-1)(x+3) so x min … us one is zero and x plus three is zero, which gives you: X=1 OR X=-3. + 3 others found this useful. Karthik Sreeram Kannan. T.A.G.

- Rules. 1  All non-zero digits are significant. For example: 2  Zeros between non-zero digits are significant. For example: 3  Zeros to the left of the first non-zero digit are not significant. For example: 4  If a number ends in zeros to the right of the decimal point, those zeros are significant. For example: 2.0 (2 sig figs) 2.00 (3 sig figs) {This signifies greater accuracy.}. If a number ends in zeros to the left of the decimal point, those zeros may or may not be significant.

- Zero puts up with a lot of shit. He's super close to the number epsilon, but no matter how close they get, everyone thinks he's a lesser being. As a result, he can never stay positive, despite being arbitrarily close to his positive friends.

- Let's try this out with the limit as x approaches zero of sin(x) / x. Both functions go to zero as x goes to zero, so we can use L'Hopital's rule. We have the limit as x approaches zero of sin(x) / x is equal to the limit as x approaches zero of d/dx (sin(x)) / d/dx (x).

One divided by infinity is not zero? [duplicate] Zero probability is not the same as impossible. $1/\infty$ is undefined, so you have to define what you mean, and you seem to be equating it with zero in a sense. That's not a completely wrong interpretation of it as long as you have a deep enough understanding of the underlying structure. – jdods Jul 24 '15 at 14:02.
